Zentek Announces the Development of a New Graphite Gel-Based Fire-Retardant Product and an Exclusive Licence with Altek Advanced Materials Inc. for the US Market
None
On November 5, 2025, Zentek announced the development of a new graphite gel-based fire-retardant product, GraphGel™. The company has signed an exclusive license agreement with Altek Advanced Materials Inc. for the commercialization of this technology in the United States.
Key terms of the agreement include: - A 5% royalty payable to Zentek on net sales. - A minimum annual royalty payment of $1,000,000 required to maintain exclusivity, effective after an 18-month ramp-up period. - Altek will be responsible for funding further development and managing the regulatory approval process.
The product has successfully undergone ASTM E84 testing, achieving a Class A fire rating, and performed well in a live demonstration in California. Altek is led by Zentek's former CEO, Greg Fenton, and plans to incorporate GraphGel™ into its "Wildfire Guardian" fire management solution.
This news is materially positive as it introduces a new, distinct product vertical with a clear path to potential revenue, diversifying Zentek's technology pipeline beyond ZenGUARD, Albany Graphite, and Triera's aptamers. The licensing model is particularly advantageous for Zentek, as it outsources the significant costs of final development, regulatory approval, and commercialization to Altek. This structure mitigates cash burn and execution risk for Zentek on this specific product.
Reviewing the historical context is crucial. Zentek has faced significant, multi-year challenges in commercializing its flagship ZenGUARD HVAC filters, primarily due to shifting regulatory pathways in Canada. While the company continues to advance ZenGUARD and its other projects, this Altek deal represents a tangible step toward revenue generation on a new technology. The minimum annual royalty of $1M, though 18 months away, provides a future baseline for revenue if Altek is successful.
The involvement of former CEO Greg Fenton at the helm of Altek is a critical detail. His departure on September 3, 2025, was explicitly to lead Altek and commercialize Zentek technologies in the US. This agreement is the first concrete product deal to emerge from that strategic shift. While Fenton's deep knowledge of the technology is a positive, this is a related-party transaction. As analysts, we must question if these are the best possible terms or simply the most convenient. The success of this product is now tied to the execution capabilities of a private, newly-formed entity.
Overall, the announcement is a positive development that adds a new "shot on goal" without draining Zentek's limited cash resources. It validates the company's R&D capabilities but does not alleviate the immediate pressures of cash burn or the ongoing commercialization challenges for its other, more mature technologies.
Zentek is an intellectual property development and commercialization company focused on nanotechnology and advanced materials. It operates through several verticals: 1. ZenGUARD™: A patented graphene-silver coating with antimicrobial properties intended for HVAC filters and personal protective equipment. This has been the company's flagship focus for commercialization but has faced regulatory delays. 2. Albany Graphite Corp.: A wholly-owned subsidiary holding the Albany Graphite Project in Ontario, an advanced exploration asset with a unique igneous-hosted graphite deposit. Recent testing has shown the ability to purify this graphite to an ultra-high 99.999% purity, making it potentially suitable for the nuclear and lithium-ion battery industries. 3. Triera Biosciences: A subsidiary developing an aptamer-based platform for rapid medical countermeasure discovery, with an active government contract to develop a therapeutic for H5N1 avian influenza. 4. Other Technologies: Includes ZenArmor™ for corrosion protection and the newly announced GraphGel™ for fire retardation.
